NanoString is an emerging technology capable of high throughput expression analysis of up to 800 targets in a single reaction. Cartridges for this technology can be custom designed or purchased as pre-built kits. I designed an in-silico experiment to determine the efficiency of an immunology-based kit at categorising Dendritic Cell subsets from the skin and blood using surrogate Illumina expression data. An additional probeset was then designed to further separate these subsets.
